ICOM Time Set Software - VE3WI Dave - 2021-12-02
The IC-7300 (and maybe others) has a tiny battery soldered on the board, to keep the clock running when the DC power supply is off. If the battery is allowed to completely discharge a few times it will refuse to take a charge. Then, when you fire up the radio the clock will be wrong.
There are various hardware fixes you can imagine - from easy to difficult. Or, you can just leave the PS on all the time.
Another fix (workaround?): ICOM has just released free Windows software that will reset your radio clock from your PC. This Youtube video tells all about it:
